PLUMBING FIXTURE FOR LAVATORIES.

Specication of Letters Patent.

Patented Sept. 24, 1907.

Application led March 2, 1906. Serial No. 303,780.

To all whom it mag/concern:

Be it known that I, ROBERTF. GILLIN, a citizen of the United States,residing in the city of New York, borough of Brooklyn, in the county ofKings and State 5 of New York, have invented a certain new and useiulImprovement in Plumbing Fixtures for Lavatories, of which the followingis a specification.

AThe invention relates to means for controlling the supply of Water tohand-basins and analogous 'recep.

l() tacles, and its main object is to provide'the valves for thewater-supply pipes with operating means which,

with the basin-cock, shall lie as nearly flush as practicable with thebasin-slab and project so little above the upper face thereof as topermit the slab to be Aeasily 5 cleaned. Another object is to provideself-closing valves especially adapted, to be operated by means lyingnormolly nearly Hush with the slab and moved by dcpression therein, anda further object is to provide connections between such valve-casingsand the basincocl; which shall be simple, inexpensive to manufacture-andconstructed to permit easy installation 0i the apparatus with access toall portions for inspection, adjustment or renewal of parts.

The invention consists in certain novel features, details ofconstruction,- and arrangement of parts vby which the above objects areattained, to be hereinafter described and pointed out in the claims. e,

The accompanying drawings forni a part of this speci- 0 ication and showan approved form oi the invention as applied to a hand-basin.

Figure l is a plan View of a. portion of a basin-slab equipped with theinvention. Fig..2 is a vertical section on the line 2-2 in Fig. 1,partly in elevation. Fig. 3 is a vertical section through a portion oithe basin an slab, showing the basin-cock in elevation. Fig. 4 n, anelevation, partly`ii1 vertical section, showing one of thevalve-stenisand its connected parts on a larger scale. 4 n

Similar letters of reference indicate the same parts in all the figures.A

A is the basin-slab, B the bowl and C the back-slab. The basin-slab hasa central opening aior the basincock or spigot D and on one side anopening al for the 5 hot water valve and opposite thereto an opening alfor the cold water. In each is a push-button by which its valve isopened to admit water to the cock. Both valves are alike and adescription of one will sulllce,

E is the valve-casing having a downwardly projecting scat E sunounding acentral opening e through which water is received from a chamber E2connected by a union at E3 with the supply-pipe E4. into the *upper endof the casing is screwed acylinder F having a stuffing-box I"1 at itsupper end.

G is a casing screwed upon and inclosing the cylinder F and extendingthrough th opening al, terminating in a flat collar or flange Gl lyingupon the upper face of the basin-slab and held to the latter by a nut Gfon the exterior oi the casing G beneath the slab. The interiormid-length portion of thedasing G is smoothly iinished toiorm a cylinderG3 and is provided with a stufling-boxv G4 in the diaphragm G5v formingthe bottoni of the recess g in the upper end oi the casing G.

H is the main-valve, consisting of a disk of leather or analogousmaterial supported in a shallow cup Hl of metal secured at the lower endoi the valve-stem I extending axially through the valve-casing E,cylinders F and G3 and their smiling-boxes and terminating in apush-button Il in the open upper end or recess g of the casing G. Thestem I carries a piston I2 matching to the cylinderFand at a higherlevel:i similar piston l3 matching to the cylinder' 'lhc valve is opened bydownward pressure on the button ll and closed automatically whenreleased -by a spring .l inclosing the stem and abutting against thestuIling-box F and piston I3. Slow closing effected by the action o thepistons I2 and I3 inthe cylinders lr1 and G3, the lowerniost forming aWater-check and the uppermost an air-check, air being admitted throughthe aperture g1. At the lower end of the valve-stein is a con'e'I4immediately above the main-Valve H, serving gradually'to reduce the areaof the opening through the valve-seat as the valve closes and thusprevent hainmering or chattering. j

A tubular arm E5 extends laterally from the casing E above thelmain-valve and is either joined directly to a branch Ll on the shell L,or is connected thereto by a pipeE, as shown, to convey Water to thecock D. The latter is a flattened spout lying close to theslab andprojecting over the edge oi the bowl. screw-threaded pipe D extendingthrough the opening o and having a flat smoothly rounded fiange D`-lying upon the slab and ironrwhich the spout extends, A squared collarD3 on the pipe engages the-opening u and the whole is firmly held by anut D4 on the exterior et@ the pipe Dl engaging the under face of theslab On the :lower end of this pipe is a tubular extension D5 of Itforms part of a long as the valve is depressed-fand so much longer as isy required by the water pressure and the spring `to reseat the valveagainst the opposition of the Water-check at F and the air-check at Gf.The duration o this closing movement may be so conditioned by the forceof the spring and resistance of the checks as to permit a sutiicientiiow to the bowl-for a usual supply by simply depressing the push-buttonand immediately re' leasing it. In any case the automatic action oi thevalve v tends to prevent unnecessary waste of mater.

To prevent a continuous wasteful lbw due to holding the valvein theextremely depressed position by.the application of a Weight to thebutton or otherwise, an vauxiliary-valve-seat E is providedin'the'chamber Il2 and a second .Qr auxiliary-valve K i's'wapplied tothe valve-stem below the main-valve H, the effect being to shut off thesupply if the valvestem be :held down to the extreme limit of itsmotion. i'

The/construction avoids the objectionable projec- 'tions of the usualstop-cocks, bibs and controllingdevicesand permits adegreeloircletjnlinsss and neatncss of appearance not 'otherwiseattainableA By disengaging the unions E3 and lopsening the nuts `G2 G2,D4 'and D the valves,"casings, and connections to the cock may be easilyremoved and examined, adjusted or repaired. I

The valve-stem with its valves and pistons are assembled andheld asshown in Fig. 4;:the straight-line arrangement affording simpleandeconomical construction`.

It will be noted that the pressure oi the water tends to seat themain-valve, thus lessening thedanger o leakage, and also that the'cylinders F and G3 of the water and air checks open downwardly thuspermitting any water to escape and relieving the stuffing-boxes. The aircheck may be dispensed with if preferred, relying upon the water checkalone to retard the closing movcfy ment, and the auxiliary-valve K andits seat El' may' also be omitted.
